What is acceleration of center of mass of two-block system

Reference no: EM13551637

Two blocks of mass m are suspended vertically as shown (one block by a spring, the other block to the first by a string), and initially motionless. An instant after the string is cut: (a) what is the net force on the two-block system; (b) what is the acceleration of the center of mass of the two-block system?

Find the consisting of the platform and its population : A 101-kg horizontal platform is a uniform disk of radius 1.97 m and can rotate about the vertical axis through its center. A 67.9-kg person stands on the platform at a distance of 1.19 m from the center and a 27.3-kg dog sits on the platform near the..

What is the new rate of rotation of the turntable : A turntable has moment of inertia 0.0300 kg m2 and is rotating at 25.0 rev/min. A 0.300 kg ball of clay is dropped vertically onto the turntable and sticks at a point 0.100 m from the center. What is the new rate of rotation of the turntable?

Assume that strings do not slip as the tension is applied : A child\'s top is held in place, upright on a frictionless surface. The axle has a radius of r = 3.96 mm. Two strings are wrapped around the axle, and the top is set spinning by applying T = 3.15 N of constant tension to each string

Change in radius is very small relative to initial radius : A solid brass (bulk modulus 6.7 x 10^10 N/m^2) sphere is subjected to a pressure of 1.0 x 10^5 Pa due to the earth's atmosphere. On Venus the pressure is 9.0 x 10^6 Pa. By what fraction change in radius/ initial radius does the radius sphere change w..

What is acceleration of center of mass of two-block system : Two blocks of mass m are suspended vertically as shown (one block by a spring, the other block to the first by a string), and initially motionless. An instant after the string is cut:

The magnitude of accelaration due to gravity : A small object oscillates back and forth at the bottom of a frictionless hemipherical bowl. The radius of the bowl is R, and the angle theta is small enough that the object oscillate in simple harmonic motion.

Angular frequency would it oscillate : A spring is compressed by 0.0541 m and is used to launch an object horizontally with a speed of 2.80 m/s. If the object were attached to the spring, at what angular frequency (in rad/s) would it oscillate?

Find the maximum acceleration without truck leaving ground : A 100kg truck is pulled across rough ground by a rope angled at 30 degrees to the horizontal. The coefficient of sliding friction is .34. Find the maximum Acceleration without the truck leaving the ground.

What type of differences are there between these geometries : Why do proto-stars, black holes, X-Ray binaries with jets, active galaxies and quasars have very similar geometries (i.e. how they appear)?
